1!) (NZ 11/77/0777, it 721/07 concern:

Be it known that I, CHARLES BARRON SAL- YER, a citizen of the United States, residing at Warren, in the county of Warren and State of Pennsylvania, have invented new and use ful Improvements in Time-Controlled Apparatus, of which the following is a specification.

This invention relates to a time-controlled apparatus, the object being to provide a simple and efiective device of this character which can be used in various connections' One advantageous use to which the apparatus may be put is for operating an electric switch, and in the drawings I have shown an organization of parts for securing this function. It will be understood, however, that the invention is not limited in this respect, for, as will be gathered from its title, it may be effectively employed in many other connections.

be supported in any desirable way. For,

this purpose I have indicated a bracket, denoted in a general way by 2. The bracket 2 has an outwardly-extending base, in which one end of the guide-rod 3 can be stepped, the other end of the rod passing through a perforation in a screw 4, threaded into the body of the bracket near its head. The head of the bracket is laterally disposed and is represented as provided with a hook 5, from which the clock 6 may be suspended. From what I have hereinbefore stated it will be evident that I do not restrict myself to supporting the different parts of the apparatus in any particular way. I have described in detail one simple means of carrying the said parts. The clock 6 is of the familiar alarm type, and hence a detailed description of the same is not necessary, only to state that it involves the usual winding mechanism, the setting device for which is denoted by 7. I have alluded to the setting device for the reason that it cooperates with a latch, as 8, the purpose of which will be hereinafter set forth.

Slidable upon the vertically-disposed rod 3 is a weight, as 9, which is arranged for movement or to have a working stroke from near the upper end of the rod 3 to near the lower end, the weight being adapted as it descends to strike and'operate an object, such as an electric switch. I have illustrated two such switches in Fig. 1 of the drawings, each being denoted by 10. The free ends of the levers of the switches are arranged in the path of the weight, and it will be apparent that when the weight strikes the levers they will be operated. In the present instance the action is-such that when the levers are operated the lights controlled by said switches will be extinguished. This, however, is immaterial. To receive the impact of the weight, I provide a buffer, as 11, upheld by or resting upon the outwardly extending foot or base of the bracket 2 and upon which the weight is adapted to lodge when it has operated the two switch-levers to the requisite extent.

The upper end or top of the weight 9 is reduced, and the reduced partof the weight is straddled by the lower forked end of the finger 12, screws, as 13, passing through the branches of the fork of the finger to pivotally unite the latter to the weight. The finger 12 has its free end hooked to engage over the short arm of the lever or latch 8, which latch when the apparatus is set is held against motion by the setting device for the alarm mechanism of the clock.

The screw 4, in addition to serving as a support for the upper end of the rod 3 or as a means for preventing its vibration, also constitutes a pivot or fulcrum for the latch 8. To provide for the proper engagement by the latch of the finger 12, the short arm of the latch, as shown in Fig. 3, has an inwardly disposed lug or extension, as 8, to be engaged by the hooked end of the finger 12.

To set the apparatus, the alarm mechanism of the clock will be wound, after which the long arm of the latch 8 will be placed under one of the wings of the setting deviceor stem 7. The weight 9 will be then lifted and the hooked end of the finger 12 will be engaged with the lug 8 upon the short arm of the latch. The alarm mechanism will then be set to operate at a desired time. When this time is reached, the setting device 7 will be started, and the instant it has started it serves to release the latch 8, and consequently the weight 9, whereby the latter can drop, the weight in its descent operating the switch or switches to extinguish the lights governed by said switches.

Having thus described my invention, what I claim is- 1. In a timecontrolled. apparatus, the combination of, a rod, a screw constituting a support for the rod, a weight guided. by the rod, and a latch for holding the weight normally against motion, said screw constituting a fulcrum for the latch.

2. In a time -controlled apparatus, the combination of a rod, a screw constituting a support for the rod, a weight guided by the rod, a finger pivoted to said weight and having a hooked end, and a latch to be engaged by said hooked end to normally hold the weigl'it against motion, the screw constituting a fulcrum for said latch.

3. In a ti1ne-eontrolled apparatus, the combination of a red, a weight vertically guided by said rod, a screw having a rmrloration for the passage of the rod, and a latch for holding the weight against motion, lulcrumed upon said screw.

4. In a time-controlled apparatus, the combination 01'' a Vertically-disposed rod, a screw having a perforation for the passage ol the rod, aweight guided vertically by the rod, a latch for holding the weight against motion, and a butler surroinuling.the rod and upon which the weight is adapted to fall.

In testimony whm'eo'l I have hereunto set inyhand in presence 01 two subscribingwitnesses.
